In new version of thunderbird Having tasks with start and end dates make days appearing highlighted in calendar. Is there a way to doesn't have this behaviour ?

Hello. I've had this problem for a while now, and I can't find the setting to change it. When I click on a link to a .pdf file, I get the "Opening _filename.pdf_" box. It is default set to "Open with Adobe Acrobat DC". When I click on "OK" to open the file, it opens it properly in Adobe Acrobat. However, it also saves a copy to my desktop (which is set as the default download save location.) I just want the file to open, not save as well, as this clutters up my desktop and I have to constantly delete the files. Has anyone else encountered this? I've searched the forums but have been unable to locate a similar problem.

Thank you. Bill

We are currently considering using Firefox ESR as our default browser but experiencing a few issues and one of them is with our configured SailPoint IdentityIQ Single Sign-On Experience, which uses Basic Authentication.

Issue Description First, the login button needs to be clicked multiple times before access to the site is granted. Once signed in, the Firefox inbuilt authentication dialogue appears, prompting the user to log in again (see the attached screenshot). The landing page is only presented after clicking the login button several times. This creates a poor user experience, sometimes causing pages to load improperly. Interestingly, the same process works seamlessly in Edge Chromium.

Troubleshooting Steps Taken I have already attempted the following: 1. Temporarily disabled all custom and security settings in mozilla.cfg and config.json. 2. Temporarily disabled Firefox Tracking Protection. 3. Allowed third-party cookies for the specific URL. 4. Upgraded Firefox Version to 128.7.0 5. Since our Firefox browser is significantly hardened, I have also enabled and reconfigured the following settings in mozilla.cfg to ensure Basic Authentication is allowed, functions properly, and suppresses Firefox’s authentication prompt, but without success:

network.http.phishy-userpass-length = 255 network.http.use-basic-auth network.automatic-ntlm-auth.allow-non-fqdn network.automatic-ntlm-auth.trusted-uris security.enterprise_roots.enabled security.enterprise_roots.enabled

Observations from SailPoint Team Our colleagues from SailPoint have tested the setup in their environment, and according to them, it works as expected. However, their browser is not hardened, and they have leveraged the SailPoint UI for authentication instead of the built-in Firefox authentication prompt.

Further Investigation • Is there a specific configuration required in the user profile settings? • Network trace analysis shows 404 errors on GET requests and the following error codes on POST requests: • 302 Redirect: Mozilla Documentation • 408 Request Timeout: Mozilla Documentation

Next Steps Is there a specific security setting that needs to be enabled or disabled? Are there any particular Firefox enterprise policies we should modify? I have also attached screenshots for reference. Let me know if you need specific logs or network traces for further troubleshooting.

Only just started with Thunderbird, so hope this isn't a daft question...

Am now setting up events in the calendar. I can see how to tag events for a wide range of categories (too many perhaps), but is it possible to highlight events in different colours, please?

Outlook doesn't let you do this, but the Google calendar lets you mark them up in different block colours - v useful for showing at a glance which family members are involved in which events - a bit like the old-style office wall planners.

Lookng forward to hearing from you.

I have just noticed that the Mozilla desktop defaults to Sydney Australia for location. Why is that? It is only one city in Australia and its not the main city. The capital City is Canberra. And each State has its own capital city and time zone.

Yes i did change it from Sydney. But my point is, that Sydney is not the default city in Australia for the purposes of location. It is simply one city.

I've wanted to change settings pages background in my Thunderbird themes. I've checked that they're defined by --in-content-page-background: var(--background-color-canvas); variable. Manipulating it in developer tools works, but when I try to change it in my theme source files it doesn't work. I've tried declaring value for both --in-content-page-background and --background-color-canvas as well as overwriting it by my own variable for :root, :host and even *, of course using !important parameter. :(

Suddenly everytime I go to a website it demands to know my location and my Windows 11 settings window opens asking for permission. I have gone into the setting and tried to turn it off but it still continues. If there is no way to stop it then I will be done as a user of Firefox

Firefox on Android (and Windows) keeps signing me out of any and all accounts.

I never noticed it until last month (January '25)

Example:

-> I log in to an account (and I am talking about accounts that I have saved in Firefox password manager) -> I use the website -> I check back into the browser after 2-3 days and like magic, I am logged out. -> I go to Firefox on Windows and it keeps doing the same thing as the Android app (logging me out of website(s) even if I signed into a website(s) 2-3 days ago), It was not like this ever on Windows before I installed Firefox on Android.

Some prerequisites:

1. My enhanced tracking protection level in Firefox is standard.

2. I only use one extension: Ublock Origin on Android. (and A LOT more on Firefox Windows, some of which are ViolentMonkey, Return Youtube Dislike, Search by Image among others.)

3. I do not have private browsing always on for any tabs or pages I open.

4. I do not have 'delete browsing data on quit' switched on for any setting (history, cookies, etc).

5. Firefox is my default browser.

6. I have not cleared cache or storage from Firefox.

7. I do use Firefox on more than one device. One is this mobile and another is on Windows. Both share the same Firefox account. (and I AM having issues on my laptop as well in terms of having to sign in a difference of 2-3 days.)

8. Firefox on Android and Firefox on Windows are both up to date with latest versions installed.

9. No kind of battery and/or app restrictions are imposed on Firefox on Android.

10. The 'Remove permissions if unused' option is unchecked in the Mobile Settings for Firefox Android.

Firefox on my Laptop (Windows) was facing the same issues ever since I installed Firefox on Android, it would keep logging me out of websites within a gap of 2-3 days.*

• Update: As of 20th Feb, '25 It has been 4 days since I uninstalled Firefox on Android and so far I have not faced sign-outs/log-outs on any websites in Firefox on Windows and websites that I logged into a month ago are still logged in with my account credentials.

Part 2:

Firefox on Android keeps reverting back to Factory settings and keeps logging me out of the app as well as signing me out of my Mozilla account

It started off with me only getting signed out of my accounts on mobile but now Firefox itself keeps reverting back to it's default setup AND keeps signing me out of my Mozilla Firefox account and the Android app as a whole. (my session/profile keeps getting removed from Firefox Android)

Things like:

1. Theme changes back to 'Follow Device Theme'

2. Permissions change back to default (stuff like 'Allow screenshots in private tab' whilst still being enabled, like I intended it to be- does in fact not allow me to take screenshots in private tab anymore until I flick that permission from enabled to disabled to enabled again. So it looks enabled but it is still set to function on the default perm - which is disabled for new user- only problem is I am NOT a new user and this happening because Firefox on Android keeps signing me out of the app and my Mozilla account as well as deleting my preferences.)

3. Site Settings are all reset and back to their factory default

4. Firefox Suggest and similar search settings have default permissions

5. Whenever my Firefox reverts to it's default settings like this, it has trouble syncing to my laptop (both use the same Firefox account) and syncing up the tabs from the laptop on this, or even just the data like history and passwords too.

6. Anything I might have disabled/enabled in any type of setting(s) is reverted to default. Nothing stays persistent anymore.

This Firefox reverting to factory settings thing has happened thrice already this month (February) and I feel hopeless, frustrated and lost.

Update: I tried installing Firefox on Android again on 17th Feb, '25 and when I signed in with my Mozilla Firefox account- it treated that mobile/Android device as another one than the one my Mozilla Account recognised as my mobile account (which is named 'Firefox on my realme phone') and since it recognises it as a different account, the tabs that I had opened in my original Android Mozilla profile/account are now gone as seen in the attached second screenshot- 30 tabs.)

Update: As of 20th Feb (the day I am writing this), '25 It has been 4 days since I uninstalled Firefox on Android and so far I have not faced sign-outs/log-outs on any websites in Firefox on Windows and websites that I logged into a month ago are still logged in with my account credentials.

I apologise for my english for I am not a native speaker, I will co-operate with any volunteers who can help me solve this problem. Thank you so much in advance! <3
